Abstract
A temporary fixing structure includes recesses formed with a mounting hole of a first tubular body to face each other wherein the diameter of the mounting hole extending along the recesses is smaller than that of a flange, and protrusions arranged at the head of an end portion of a second tubular body wherein a spacing between the protrusion and the flange is substantially equal to the thickness of a mounting surface of the first tubular body and wherein the protrusions are arranged inside the fist tubular body through the recesses. The second tubular body is turned with respect to the first tubular body to bring a flat portion of the flange into close contact with the mounting surface of the first tubular body.
